    Pedal Output Impedance

    I recently bought a Way Huge Pork Loin, and just saw in the manual where it says the output impedance is < 25k ohms. That’s quite a bit higher than most other high-quality pedals I’ve seen. That makes me a little worried about high-end loss when the pedal is active, since I run a 15-20 foot...

    The Wiring speakers minefield

    I know there is a very informative thread on impedance and wattage on here somewhere, but I want clarify something. I’m looking to build a 4x10. Each speaker is 250 watts at 8ohms If I wire in series I’m going to drop the impedance to like 2ohms, which will kill my amp in the long run If I...

    2 channel power amp with two 8ohm cabs (Impedance)

    Looking for some assistance with impedance when it comes to power amps, specifically a Peavey IPR2 2000. I'm familiar with impedance in that when I run two 8ohm cabs with a one channel amp, the resulting load is 4 ohms into each cab. I get completely lost though when the option is using a power...

    More Volume, Same Tone?

    I have a 1972 or 1973 V4 that I absolutely love the tone of... but I play in a band that's goal is to be as loud as possible (bluesy/doom metal). I currently run the amp into two separate 4 ohm cabs for a total impedance from the amp at 2 ohms (max output) - which is already pushing a lot by...

    impedance questions (4 ohm amp into 8 ohm cab)

    When Pedals Change Your Output Impedance

    I started a thread about input/output impedance years ago and I have a follow up question. If you have a buffer in your bass, or in the first pedal of your signal chain, with a very low output impedance, this is considered a good thing in terms of being able to drive long cables without signal...

    Would overpowering by 0,2 Ohm cause any problems to a tube head?

    Would using a cab that measures 4,2 Ohm impedance in a 4 Ohm speaker output on a tube head cause any damage or any other undesirable effects, or is 0,2 Ohm so insignificant that it won't matter at all?

    SVT impedance question

    Hey guys just a quick question. I've always used cabs with matching impedance so I've never put much thought into mixing it up. I currently run a SVT-CL through an old ampeg B25 215 cab (4ohms). I also have two 210 cabs (8ohms each). I know that all 3 cabs would be 2 ohm load. Can I use this set...

    Running Two Four Ohm Cabs

    Double Bass Impedance matching for Realist pickup
