JJ Marshall JMP / JCM800 50Watt Retube Kit

16 November 2019
I bought this Retube kit for my JCM800 20watt Studio Classic Amp Head cuz the original power tubes were starting sound a little noisey. I swapped them over (NO BIASING REQUIRED for these amps) and it bought the amp back to life and sounding great.

Great Tubes / Great Service

I tried the JJ tubes on Joe Bonamassa's recommendation & I wasn't disappointed. Very quick delivery as well, thank you Evatco!
