The mid control on the real crunch/dookie amps actually filters down the mids quite a bit. It is an interesting circuit compared to a stock 1959/2203 as the controls have a big sweep of change compared to the stock counterparts that don’t really have much adjustment. Adding gain to the amp also adds some low mids that you hear in every Green Day record as well. But back to the mid control, on 0, it sounds like there is a blanket over the amp. The settings I like to use for dookie tones vary from the left to right speaker but generally: gain:6 bass: 5.5 mid: 3 treble:5 presence:5.
Jerry Finn did use a pultec eq on the record, but per the album’s engineer, it was a very dry record with not much post adjustment.
Per John Suhr, tolerances were tight on components for the mods and the preamps while he was at CAE. He told me he would pull out a perfectly good vintage power transformer from a donor amp just so he could have the voltages he wanted in the amp. He mentioned that once he left, he saw a few examples of martins amps that weren’t as tight on tolerances of components.
Mine was done in the early 90’s and is comparable to the first run of CAE 3+SE preamps. Not sure which version was used to model for fractal though. Once I am able to post links, I will happily attach some more clips of my amp.
