troubleshooting

As I mentioned in a separate thread, I recently purchases a Mesa/Boogie Subway TT-800. I love the amp so much, the Boogie channel has that deep vintage bloom that I love, and playing through a punchy Phil Jones 8x5 is the icing on the cake. However, I bought the amp new and since I received it...

I’ve been experimenting with a new setup, and experienced a loud recurring popping sound from one of the speaker cabs. I’ve got a GED2112 preamp going to a crest power amp, powering one 2x12 and one 1x18. The amp channels are set to max and the preamp channels are at about 1/4 gain. This is...

Hello, Many months ago I built a Hjart Müller overdrive kit, dead upon completion. I pulled it out today to find I had forgotten one wire. Soldered the last wire and Eureka, sound. But something is off. Before I bore you with the details I have one starting question. When measuring the...

Hello! Long time lurker, first time poster. I have been having a hell of a time trying to add distortion to my pedalboard. However, no matter what I do or what distortion pedal I use it’s always giving me hiss/hum to the point of being unusable. I’ve gone thru all the normal troubleshooting...

I'm trying to troubleshoot an issue with a Schecter Stealth-4 that I came across. Bass is mechanically and visually fine with good setup. It is a P/MM with Master/Blend/Treble/Bass controls. Exterior visual inspection is good, no obvious damage. Pickguard still has protective plastic on it...

Hi there! I'm curious if any of you seasoned iPhone and iPad users can assist with an easy question -- is there a way to adjust the length of the "long press" it takes to activate edit mode on an iPhone or iPad (when all the icons get squiggly so they can be moved or deleted)? A family member...

Hello everyone, Have a bit of a newbie question. I've always played passive basses, but recently picked up an active charvel. I tried plugging it into my axe fx to record and test it out when I brought it home, and it wasn't making much sound beyond a crackle through the axe. I then realized...

I plugged my bass into the headphone jack on my amp, and it will now not produce sound. Turning on the power switch results in a low, almost heartbeat sound from the amp, but the power indicator does not turn on. Did I kill my amp? Is there any way to fix this?

Hi, so I'm trying to install new pots in my jbass and am running into some kind of problem. All the wiring has been done correctly as far as I can tell but something isn't right. My neck pickup has no sound at all and my bridge pickup is buzzing/humming like crazy. The tone knob makes the hum...

Hello bass amp heads, I bought my SVT in basically new condition from a friend who barely used it, and now after about a year I've started to encounter some issues that I'm hoping to fix myself. I first started noticing a problem about a month or two ago, where occasionally playing a C on the...

Hello! I have a bassics bpa-1 which I love….has a prob. I was using a zoom b1xon i plugged into the effects loop of the bassics preamp. Sounds ok and no prob. Then the preamp shut down. Checked the cable …..the off on switch…..everything looks still ok. No burning smell. Wondering if the zoom...

Hi there, all. I need a bit of help with my bass. I built this thing custom using Warmoth parts a few years ago. It's got a J neck pickup and an MM bridge pickup, and active electronics. I sounds great, but obviously I don't have a whole lot of support when it comes to fixing it! Hopefully...

I have had the bass for over 8 years. I replaced the original pick-ups with Demarzio's when I first received the bass. It just started doing this. The E and A strings sound fine when plucked but the D and G strings break up or don't sound at all. I tested it on a couple of amps as well as...

Hey everyone, I was curious if anyone ever experienced their 800rb’s bass and boost pots cutting out past the 3 o’clock position. The sound is still there, but seems to lose the bass and boost feature when cranked past a certain point. Almost seems like it’s clipping but I’m doubtful. I’m...

Maaaan I haven't posted here in a long time - but I recently have been on sort of a bass kick lately, and I ended up picking up a new (to me) cab, since I found a good deal on a used powerhouse 4x10. I haven't had a chance to get it up to jam-level volumes, but it's been sitting in my living...

So, I got an Ibanez SR900 in my repair shop, where somebody swapped volume pot and installed Bartolini MK1 pickups (not sure if they are stock, neck and bridge has been soldered vice versa). I soldered them intuitive "right" places, according to directions of ballance pot, and stumbled upon a...

Okay, so this is strange. I've seen similar threads, but I'll include everything I've already checked. I don't know what else to check. So at first it was a popping and buzzing sound whenever I touched metal, knobs and bridge. Now, I have no sound at all coming through the bass amp. Bass and...

Bought a barely used svt-cl in late 2018 and had no problems with it until earlier this year. First, once when I was playing the volume suddenly drops significantly and most of the lows cut out. The sound could best be described as weak and distant with some fuzz/hissing. No squealing or popping...

I run a MB Blackline 250 through a MB 4x10 cab for three years now and have been running into an issue lately that I haven’t experienced before. My amp turns on fine and all my cables seem to be in decent condition but I’m not getting any sound until right when the amp powers down. It seems to...

Hey, I just started playing bass a few months ago. I got sterling ray4 sub series bass, and I've been using a fender rumble 25 bass amp for the past 2 weeks. I had it set to the volumes I like for playing in the house, and haven't touched it. All of a sudden, it is putting out sound at about 1/3...

Saw a good deal on a used one of these and pulled the trigger- I am now the proud owner of this Hantek DSO5072P: Not sure what the most common uses are for this thing- any ideas for cool stuff to try in the music realm? Most oscilloscope threads I found here mostly relate to what to buy...

Hey all, I have a Cliff Burton edition Morley Power Fuzz Wah pedal that isnt functioning. When I went to practice one day the led's on the pedal flickered and then the pedal stopped working. I read somewhere that if the led'd stop working the pedal won't work? Please help! Thanks!

I bought an Ampeg 810e cab two years ago, and it has played amazing for me . Tonight at practice, we noticed a strange noise coming from my cab. It is a crackling , almost dirty pot sounding noise. It doesn’t sound like a farted out speaker . I was playing decently loud, using a Hartke LH1000...

Well, after lots of time and money, I finally have my big pedalboard set up for stereo. Yay! Sounds amazing, except for one thing. I have an American Loopers bypass looper, a pretty big one, has 6 mono loops and 4 stereo. Now, for a reason I can't figure out, whatever pedal is on loop 10 (the...

Always read the f***ing manual. I did not. I had the amp in operation and switched the output power selector from 100w to 25w, then the switch arced, amp went silent and i blew some fuses and power tubes. I replaced said fuses and tubes but those tubes immediately blew as well. No warranty...

My amp is an Ampeg BA-210SP (not the V2). I purchased it used. It has a bad hissing problem. It hisses even when the bass isn't plugged in. The volume and treble controls increase the volume of the hiss. I took it in to the shop but it didn't hiss there. It also makes crackling sounds...

I need some really basic help with the FI. I've connected my Saffire Pro 14 to my 2012 Macbook Pro running Mavericks and I've connected my FI to the interface using a Hosa MIDI cable (properly, meaning interface out is connected to FI in and FI out is connected to interface in) but there seems...

I play with Boss GT-10b and use a lot of the amp models. Consequently, I usually plug straight from the main output into the effects return of my amp. But I'm starting to have problems with amps. My MB 800 has a transistor that keeps going bad and I wonder if somehow I'm forcing current...

hey guys, I'm having some issues with my bass rig as far as grounding goes. I run a full mark bass set up everything is rack mounted on the head end. when i plug both my in ear monitors and plug in the xlr into the direct out i get a wicked 60 cycle buzz through the pa (doesn't come through the...

I am a bassist first and foremost so I hope you can take that into account.....at my gig, where I play both bass and guitar, one of my tube amps had an event, and it doesn’t seem like a tube. The amp that failed was my 15watt blues junior- brand new. I had the master at about 2 and the volume...

Hello everyone. Today I was doodling in my living room with my gear and I did not take the pedalboard off its bag, so I plugged straight into the amp with a cable. I immediately noticed something was different in my tone. I then took my PB out and plugged the G10...whoa, it sounded like all the...

So I recently changed the strings on a Squier J-Bass V two days ago and ever since the new set has been on when I turn the pickups up 100% the signal sounds really distorted. I'm wondering if this is a pickup problem or whether it simply is just the new strings being a little too alive whilst...

I recently purchased an Ampeg B3, the one with a 15" speaker and an 8" one. I tought it was a good deal however when I first tested it, I noticed how the amp produced some kind of buzz whenever I played high notes, anything on the G string would cause a buzz. Aparently the buzz is coming from...

Hello, I am new to this site & this is my first post. I'm having some issues with my Ibanez SR506 (six string) bass guitar. Last night I noticed that my bridge pickup had a serious loss of output signal so I had to switch over to using only the neck pickup. It has active Bartolini pickups. Has...

Hey! I´m having this problem with my pedal, I have a DOD Bass Stereo Chorus fx62, it was working great, i was playing with my effects chain but suddenly it just stopped sending any "chorus" signal, but it still turns on and makes that "clicking" noise when it is engaged or disengaged ¿What can...

Hi everyone, we evenly acquired some used gear a bass guitar (Warwick) and bass amp (orange ad200B with 810 cab). While trying to set up the bass we had an issue in which the audio jack in the bass where the cable goes in wasn’t being held in properly and popped out. This led to an uncomfortable...

Occasionally over the past year, while playing my Stingray through my Ampeg SVT 3 Pro and 210HE, my signal has dropped quickly (sort of like turning down the volume on the bass quickly, but not instantly), and then when it comes back (I can't establish why it comes back, I shake cables, turn...

just installed the TCM4 in a new build, and all is good in passive mode. However when I turn on the preamp (volume knob push/pull) I have no sound. Fresh batteries, I've double checked the wiring. Any ideas?
