impedance

Hi, I have a EBS Reidmar 502 It can handle a 2 ohm load. I want to use a 8 ohm and a 4 ohm cab together. The Reidmar has one speakon output only. If I go out of the EBS into cab one and from that into cab two, are those cabs now connected in series? I know the math but I am confused about...

Hey all, I'm interested in buying a Behringer Toro and Behringer MIDI footswitch to use alongside my bass guitar. Into the same amplifier with an ABY. As far as I know, it will work. But I need to know if there will be any impedance problems. My pedalboard only runs through by bass guitar. And...

I swear I wasn’t in the market for a new head. I just ordered a GSS Baby Sumo power amp to be used in conjunction with a Laney Digbeth pedal, and I was in the sho p to buy a Laney N210 cabinet. Then this Nexus SL showed up, at an insanely low price (I mean less than what I paid for the Digbeth...

to hook up my tc electronic thrust 500 to my 2x10 fender rumble v3? No idea about speaker cables. Couldn't find anything specific online. What is typically used, what hould I know about speaker cables? Thx in advance!

I'm trying to get my upright bass ready to play out. It has a piezo pickup installed and I have an Avenson Audio Small DI also attached to the tailpiece. The Avenson D.I. is GREAT for going direct - it uses phantom power and a JFET. It has 10Mega-ohm input impedance and XLR out, with unity...

Hi TB, I have a question about cabs. Guitar cabs, to be honest. I hope that's ok. Let me know if it's not. I recently got to try the weber black shuck speakers and I was very impressed. So much so that I made plans to build a 2x12 guitar cab with black shucks to be used together with a 2x12...

Hi all, and sorry if think that you have heard this one before... I have two Ampeg cabs, an SVT 210AV and a PF-115HE. They are both 8 ohm, so if I chain the two the resulting impedance will be 4 ohm. I'm planning to use these cabs with an Ampeg PF-500, which at 4 ohm is rated 500 watt. Now the...

I have a Markbass 103 combo that puts out 500 watts @ 4 ohms. The 3 10" speakers are 6 ohms total and they list the amp as having 400 watts at that impedance. Of course the manual warns not to go below 4 ohms. I have a genz benz 12" cab that is 8 ohms, if I plug that into the ext...

Hi, so basically I have an M-Vave (a.k.a. Cuvave) Fuzz pedal in my signal chain, I usually go fuzz first in the chain, and I usually use my trusty Sterling by Musicman SB-14 bass, which has super high gain, which I believe translates to low impedance (please correct me if I'm wrong, I'm fairly...

I plug my double bass's Realist lifeline pickup into my Radial Bassbone OD to great success, with the 10 meg ohm input impedance capabilities. I'm planning on building a pedalboard for upright and electric, and was thinking about using a small 2 input passive junction box/patchbay for my...

Hi. Another impedance question (sorry!). I have a Traynor Bass Mate YBA-2B amp and speaker combo (early 70s). My goal is to take a direct signal out in to my computer/DAW (for use with an impulse response) for recording. The Traynor internal speaker is 8ohms. I have one output on the back of...

Recently, I decided to go down the path of having a pre-amp + power amp setup due have a bit more flexibility with my wattage, sound, setup, etc. It didn't take me long that the pre-amp I was interested in, the Radial Bassbone OD (convenient because I am a frequent doubler) would not drive the...

So I bought myself a darkglass alpha omega 900 head and I'm currently waiting for it to ship. I did notice afterwards that it has a 4 ohm / 2 ohm switch, so I got curious, however, I can't find what power rating the 2 ohm setting has. 8 ohm is rated at 450w (I think), 4 ohm at 900w and 2...

So I just bought an obscure single 15" ported cab with an Electro Voice Force speaker. It's a Dean Markley 115FH which I guess is quite similar in design to a Music Man 115RH cab. If I plug the main speaker output on the B25 with a "Dummy Plug" and then power the speaker from the extra speaker...

Hello, I have a question regarding the safety of running a 5.33 ohms load? Both of my bass Amps can handle a load of 4 ohms which I've seen on other threads is "close enough" to 5.33 ohms to run an 8 ohm and 16 ohm cab together, but my question remains. Is this safe? For example on the Hughes...

New Guy here! Gear head, not tech. Please help? I have 4 8ohm drivers and I want to run them off my early 70s Blackline SVT head. I know the guy I want to talk to is familiar with it. Standard would be a 4 ohm load, If I understand correctly plugging into the secondary speaker outlet...

What might happen to a '73 SVT from being played through an SVT cab (an old one with the 32 ohms CTS speakers) that only has 7 speakers, doing that for maybe about 50 hours over several months? The amp's starting to sound a little flubby (you know what I mean, right?) and muddy. I haven't taken...

Hey TBers! Your input would be greatly appreciated. I bought a used Orange OBC 410 a while back. Sounds amazing with my Traynor YBA200-2 tube head. A few jams in, I started getting low distorted volume as if a mismatch in impedance. Plugged the traynor into another cab.... same issue. Then...

Two cabs, each 8ohm. Connecting parallel maths is easy: 2x8ohm=4ohm. Does anyone know how to calculate load when connecting series (I understand it's also called daisy chain?).

My ric 4003 has pretty low output, which causes some interfacing issues with other gear I have. I don't really want to use a separate di/preamp box, so I was wondering if installing a pre-amp on my bass like darkglass or bartolini preamps (or whatever brand). My goals are to have impedance...

Hey there, I'm not only new to this forum but also fairly new to bass playing. I've been a blues guitarist for 35 years and started playing bass in October 2018. I'm completely self-taught, both on guitar and bass. My big hero on guitar is Jimmy Vaughan and my main bass hero is Keith Ferguson...

Talking about cabs that are able to swap between 8 ohm and 4 ohm, via a button or switch or something. Does such a thing exist? If so can someone give me some names cos I’d love to take advantage of this technology. Imagine, u have 1 head, and 1 cab, that u can use for both practice, jamming...

Hey everyone, this thread might already exist, if so please refer me to it, if not, lets kick off the discussion. So here's the thing, I have recently purchased Aguilar TH500 top and I want to pair it with 2 SL112. I know that TH500 runs following config: -One 8 ohm cabinet – 250 watts -Two 8...

The bass-related part is at the end. I'm posting on a few forums, in hopes of advice. I have a '65 Vox (Thomas Organ) Berkeley V8. For those unfamiliar with it, it's basically an AC15, but with reverb. For decades I've used it with a 2x12 cabinet w/ Vox/Oxford Gold Bulldog alnicos (from a Vox...

Hi y’all I have a m9 carbine rig with a 4 by 10 cabinet. I also have a fender rumble stage 800. Is it safe to use the Mesa cabinet as a speaker extension for the rumble 800. If it’s all good let me know what settings are optimal please and thanks. Note don’t mind the ear plugs in 1/4” jack...

I’m saving up for a new amp and decided to go with Gallien-Krueger. I’ll probably go with the MB 800 head. Would it be a good idea to use a Neo 4x10 cab? If so, should I use 4 ohms or 8 ohms?

I'm considering purchasing a Darkglass Mircotubes 500 and I just had a question about Impedance. On Darkglass's website it says; "The M500 is rated at 500W @ 4 Ohms. This means that you can use Cabinets, or combinations of cabinets with an impedance 4 Ohms AT LEAST. NEVER connect a load less...

I'm trying to dive deep on my understanding of guitar circuits than my current superficial one. First question: Is it pretty useless to try to create equations for simple circuits like you would for direct current and resistor circuits? I tried doing it for these two circuits (Single...

So I own a darkglass microtube900 amp And I am running it through a hartke hydrive 4x10. I was told buy the shop that sold me the amp that this would be a fine cab to pair with the amp. There is nothing wrong with my rig but I’m starting to play bigger venues and was considering adding a hartke...

Hey all, I've had my cab break in an interesting way; Now because I'm a starving musician, I was wondering if I would run into any problems if I just disconnected the tweeter? I really can not afford to replace the tweeter at this moment as I'm paying off a transmission replacement. So...

Howdy folks, quick question. Using the SVT4 PRO bi-amp function, 4ohm 810 on one side and 2 4x10” cabs (each 8ohm) on the other side. Does the amp see each as channel separate at 4ohms or see it as 2ohms like if the cabs were wired ‘parallel’ ? thanks! -Ashtray

Searched and searched to find how (apparently) impedance of BOTH the DB pickup AND the amp have huge effects on output volume. As most of us have probably tried various gear to maximize our tone, so have I. Here's the scenario(s)... Utilizing my old 50s Framus DB and the Realist (under the...

Do any of you use Ashdown heads for double bass? The specs show it has a 3.9MOhm input impedance which from my general reading around should be great for a piezo without needing a separate preamp but I've not had a chance to try one out. A rehearsal place I used had one so I was using it for my...

Hello guys, I'm a newbie and I don't understand the speaker impedance rules well. I wanted to ask you: My amp output impedance is 6-16 ohm and I want to feed it to speaker cabinet that consists of two 4-ohm mid speakers and one 8 ohm tweeter. Is it possible to do it without damaging the amp or...

Hello, Just made an account 30 minutes ago after spending the last two days reading/ learning off this site. My question is, right now I daisy chain a 4x10” cab with a 1x15” cab. I do not have a crossover or anything fancy yet. I want to add either a tweeter or small midrange speaker to the...

Hello, I have an Ampeg SVT-7 PRO with two speaker outputs or: 600 watts (8 ohm) single output 1000 watts (4 ohm) double output. I have three speaker cabinets: 1.) Markbass 121H; 8 ohms, 400 watts 2.) Markbass 102P; 4 ohms, 400 watts 3.) Ampeg PN 210 HLF; 8 ohms, 575 watts Things I already...

So I acquired a 1969 Ampeg B-25 tube head yesterday because the tone was just too sweet. My needs remain with finding a louder setup. Apparently I am at war with myself on this issue because I went and traded for 50 tube watts, which ain’t so quiet through two 15”s. I guess for small...

Hi everyone! Well I called this thread a Volume Pedal, because I'm looking for a passive volume pedal, obviously, but I have one question - let's say that volume pedal has a high impedance input, it's mean that normally you will plug in your guitar directly into it, BUT what if I'm sending a...

I find the whole ohms law business very confusing! I run an Ampeg SVT 7 Pro head: 1000w @ 4ohm 600w @ 8ohm. I’m looking to buy a new smaller cabinet, so I’m trying to clear up my uncertainty, if anyone could answer these questions it would be great. 1. If I buy a 4ohm cabinet should it be...

Hi. Planning to buy a volume pedal, I purchased online an EB VP Junior 250k. Nere come the first mistake, I suppose, since I was planning to put it at the end of my chain and maybe I should have purchased the 25k model, right? Chain would be: Comp - tuner - od - envelope - phaser - volume...
