Question on Mark IV tone controls

I have always heard and read about the tone controls being pre-gain. So, I was playing around today trying to see exactly how much range I had in each control. On the R2 channel, I turned down its treble to zero, and then the shared bass and middle to zero. I was somewhat surprised when I still got ...

Re: anyone ever use a atturator?

There is really no install needed. Instead of running a speaker cable from your amp to the speaker(s), you run it to the attenuator, and then you run another speaker cable (NOT an instrument cable) from the attenuator to your speaker(s). Be sure not to use an instrument cable. They cannot handle the...

Re: anyone ever use a atturator?

dearlpitts, I use a Weber Mass 200 attenuator for my Mark IV and it works fine. It gives me all the volume options I need. When I want to crank the power tubes, it lets me do so without killing our pets. Very handy little device. I would recommend it in a heartbeat. I chose it over some other attenu...

Re: The Mark IV thread....!!

ostepop, According to the Mark IV manual, there are 2 tubes involved in the reverb process: V4B is the reverb send and V3B is the reverb return. The other half of V4 (V4A) is the 'second lead high gain stage'. The other half of V3 (V3A) is the 'first lead high gain stage'. If either is missing, the ...

Re: Mark IV A Manua & 6V6 Questionsl???

Rhoads, thanks. It seems I have (at best) a tenuous grip on the obvious! Yes, as you stated, my MK IV is indeed a wide-body model. The manual on the Mesa website must have been written for MK IVs before the wide-body models were produced.

Thanks again.

Re: Mark IV A Manua & 6V6 Questionsl???

How big of a difference is there between the IVa manual and the IVb manual? I have a IVb and I downloaded the manual from the Mesa website. The diagrams in the manual reference a different layout than my amp. For example, the EQ switch and lead harmonics switch are on the front of my amp, but the ma...

Power scaling might be interesting.
