Marshall JCM 800 Reissue 2203

Purchased 2 Marshalls 1959hw and Jcm 800 and very satisfied
This amp is very loud suitable for any stage, it's loud enough for any practice rooms keep in mind having ear protection may be good idea.
This amp has FX loop so you can plug delay reverb pedal into it, this really expands possibilities of amp
Combined with various cabinets it will give you all spectrum of 80x 90x 2000x sound
Don't forget about pedals like distortion overdrives and Fuzz-es
One more advice, every pedal has its unique plug-in method so if it's common to plug distortion pedal in front yet there are some distortion pedals that sound much better plugged into FX loop and vise versa some reverb pedal may be plugged into front and the final result will be different

Let's be frank This is a benchmark amp.

It has one channel, only the 'high' input will really get used (unless you use active pickups), it doesn't have endless amounts of gain, there are plenty of better choices for cleans, there's no built-in reverb or other fluff. This is an amp that does one thing, but does it so well that you won't really care.

What is that thing? Connect it to a 4x12, plug in a Les Paul, keep that pre-amp volume above 8 and the master around 3 or 4, smash that A chord and feel like the rock god you always dreamed of being.

Purists might sneer at the effects loop (don't use it then). Some will whine about the single channel (put an SD-1 in front of it and learn to use your volume control). Put simply, this is an amp that isn't built for jazz, dream pop or being contained in your small, city apartment (as my neighbours will tell you). It's meant to move massive amounts of air and melt the faces of everyone, including those in the nosebleed seats on the far side of the arena.

If you love the 800 roar, have never heard the word 'compromise', feel squeamish at the prices on the vintage market for something that'll very likely need a rebuild and are totally okay with tinnitus, here's the original (reissued).
