Our band is in a position where we expect to have to "plug and play" into existing amplifiers supplied by the club. Because of the bands we are covering (Tool, Soundgarden, STP, SOAD, etc) we need a good deal of flexibility in guitar tones. As we use rent-by-the-hour jam spaces, we have already found that we are wasting a lot of time as our guitarist tried to reproduce tones that he was getting in the previous jam space with a different amp and various analog pedals. So, I suggested that we pull out his Pod XT and try sculpting sounds using Amp simulators, and then go for the clean channel, get the driest sound with the flattest EQ possible - i.e. start with all EQ at 5 or 0 (depending on the EQing model of the amp) and dial the gain/drive to just the edge of "warmth" then pull it back a notch. We tried this with three amp models:
Marshall JCM 2000 60W combo
Marshall MG100 DFX Fender DeVille
We started with the ​JCM 2000 and got very satisfactory results. But, using the same Pod XT patch we had sculpted for that amp, when we used the MG100 and the DeVille, we had to set:
Bass=2/10
Mid=2/10
Hi=8/10
Presence=8/10
By contrast, were all at 5/10 on the JCM 2000 (I realize that "presence" means different things on different amps). I expected some minor tweaking for the obvious reasons of course, but nothing this drastic. Does anyone know the Marshall JCM 2000 60W combo, and is it the odd man out - i.e. is it known for having a particularly hi-end-focused clean channel? Since the point is to be able to get into a new room, and set up our tone as quickly as possible (especially in situations where we are sharing equipment with other bands) I would really appreciate any advice on how to approach this problem. Thanks!
