I bought a much discussed Marshall JCM 800 2203x Caswell mod. It's badass. period.
It's hard to get it to sound right due to all the different pulls and mods he did to it but basically you have a lot of tones once you figure it all out.
Clean, with a seperate clean volume.
Crunch, like a stock 800
Stage 1 mod, where its like a more overdriven 800. Perfect for hard rock rhythm
# 39 and then in the #39 channel you have 2 seperate gain toggles.
My favorite tone is on #39 with the upper gain toggle engaged. It's awesome. It's razor sharp and not fuzzy. With the 2 gain toggles engaged, its closer to Lynch territory but too buzzy for my needs.
The amp is equally great for rhythm as well as playing leads.
I just got the amp a day or 2 ago and need to get her down to the studio and record some clips.
Honestly this amp would be great for the studio due to all the tones it can dial in.
Stage 1 for rhythm and 39 for lead is pure rock n roll
or
39 for rhythm and 39 with a EQ in the loop with midboost for Lead for hard rock.
Also, for the appetite record tone the key is adding reverb. It will smooth out the tone to where you need it to be.
The tone reminds me of the cameron tone to some degree as well as the splawn quickrod tone.


My bogner 101B is now for sale.
 
Re: Caswell modded JCM 800

There was some question about what exactly Tim does for the mod - basically, if all he does is add another preamp tube
To me, this amp does a lot more than just the hot rod 800 tone, and its a lot more than just an 800 with an added tube. You can make the amp go from totally clean to screaming metal with a few pulls and toggles.
