I've done some searches but I'd like to know if anybody who's real familiar with Marshall 2203s can help me out. My situation is that I have an early 80s 2203 (JCM800) and I LOVE it. I used it in a metal band with a tubescreamer into the hi input for years before I even discovered the magic of the low input. The last 4 years or so I've been playing in a VERY LOUD band and using much much more classic rock tones. I run a bunch of OD / fuzz / boost pedals into the LOW input on my 2203 and am basically in tonal nirvana. I love this amp. The reason I love it is its loud as hell and has TONS of headroom on the low input. I have the preamp on 10 and the master between 7 and 8. The direct signal is pretty damn clean, even with humbuckers....just a bit of grit. The best part is that when I step on pedals for leads (I like rude solos) there's a huge volume increase! I love it. So anyway now I'm playing in 2 bands that practice across town from one another. The new band is playing grind / metal stuff so my 2203 went over there to be used with the hi gain input since that is a classic great tone of course. Now....I need something for my classic rock stuff with comparable headroom and volume to the low input of my 2203. Would a 1987 or super lead / super bass circuit do this? I'd really just like the cleanish cranked tone with tons and tons of headroom. I hate it when the bass notes are mushy, even with a big muff. I'd don't really want another 2203 because...well, I just want to try another flavor. So are the 4 input marshalls going to have enough headroom for me or will they break up too much?? Thanks!!
