Marshall SC20H S.I.R. #34 - TONES AND FULL DIY MOD GUIDE!!

A SC20H Studio Classic head has come in for our interpretation of the S.I.R. #34 mod. The final HF mod stays true to the core SIR #34 tone, whilst taking some of the top end 'ice pick' out of the amp. Bonus feature is a 3 way José zener clipping switch fitted to the rear of the amp. Full tone demo and detailed walkthrough of the modded schematic and pics of how to implement.
