    Did some bassmans have POSITIVE feedback?

    I was researching the bassman when I thought I didn't really have it sounding how I thought it needed to sound. and realized, in some amps the plate wires on the output tubes are connected backwards, but the output connections stay the same. particularly in Johan Segeborn's video: here's some...

    I know I need a new tube.....

    So much junk ready to buy, but who is making the quality tubes right now? I turn my amp on (Valvestate 8040) and it sounds like plasma raping the moon around Jupiter on an EM frequency. So I know I need a 12AX7.... Who makes the best quality tubes in 2022? I already wrapped the amp head inside...

    Warning for all DSL100HR/40CR owners and likely applies to smaller DSL reissues...

    So tonight i went to turn on my amp and i heard a loud pop coming from the head, not the speakers. It was 100% the head. So after some basic trouble shooting it was apparent id have to pull the chassis to find the issue. So long story short i had a resistor arching due the the dreaded yellow...

    New DSL40CR or preloved 1992 JCM900 combo?

    I've been playing guitar for a while now and it's time to upgrade my amp, which is currently a solid state vox. My two options at the moment are either a brand new DSL40CR or a second hand 2x12 JCM900 combo from the 90s. Which one would be a better amp to get?

    SOLD: Blackstar HT20r MKII 20W Amp Head, Houston area pickup

    I have a Blackstar amp I don't plan to use anymore. Shipping amps is a pain and expensive. Before I list it on Reverb, I'd like to see if there's anyone in the Houston, TX area that is interested. I bought it brand new in August of this year. It was put in the cabinet you see in the picture and...

    Laney PT30MV - Dead Input

    Greetings, I recently picked up a Laney PT30MV amp from my local Sam Ash. Upon picking it up, everything worked and sounded fantastic! Couple of days ago I noticed that the high sensitivity input is dead, nothing, no sound. The low sensitivity input still functions and sounds great. I am...

    Early Marshalls are single channel clean amps?

    Some people are saying the earliest Marshalls such as the JTM45 and other Marshalls before the 70's are single channel clean amps (so they can't distorted) but they actually have two channels which are High Treble (Loudness 1) and Normal (Loudness 2). Is High Treble basically the overdrive or...

    DSL40CR Only Works on "High" Setting

    Earlier today, we were recording drums and using the amps MP3 input to playback tracks to check over them so we weren't wasting time passing around a pair of headphones. Right at the end of the session, turned the amp off standby again to hear the last track, nothing. Turning master volume up...

    Marshall 8080 Service Help -- No "clean" Channel Sound

    Hello all, I needed to change out a pot on my Marshall 8080 and didn't want to disconnect all the wires, so I took apart the main transformer so I could manipulate the circuit board in a way to get to the underside to replace the pot. That went fine. When I went to test it, I found that there...

    Dumb Bias Probe Mistake. Used Dcv Instead Of Dca. Something Popped.

    I grabbed my bias probe, hooked it up to my 6l6 Ibanez TSA30, flipped it on. POP. Tiny amount of smoke. No sound. Turned it off. Took the probe out. Put 6l6 back in. Turned it on and all tubes warmed up. No sound... Guessing it is because I was hasty and had it on DCV instead of DCA...
