True in that these amps are good pedal amps. Dirt in front: JH-F1> TS> BoR > CM Plexitone Dirt in effectsloop: Guvnor > Jackhammer (these work very well in the loop, better than in front which surprises me). 3x TAD ECC83 in the preamp section which was a surprise as well since I expected JJs (red Marshall label). I`ve experimented with a couple of NOS tubes but these TADs are the most quiet (at 20watts cranked) so I leave them in. 2x JJ EL34 (red Marshall label) valves but these will be replaced with 2x EH 6CA7 valves somewhere next week, hopefully with pleasing result.
