My first guitar amp and still in use

Maybe a bit of an underdog in Marshall Amplifier history but I still love it after more than 30 years of using. Some say it´s one of Marshall's best solid state amp. Plenty of great tone variation and a cool reverb as well. From clean to overdrive. All works as it should and sounds great, includes a nice Celestion speaker.

best transistor amp you can get

I've heard it by chance, and after that couldn't get his sound out of my head. It responds like tube amp, the sound is clear, litlle bit compressed. PREAMP VOL - MASTER VOL combinations works so good that you don't need any OD pedals. Spring reverb. Just a great amp
