ALL VALVE. ALL ORANGE
The Thunderverb 50 Head is a Twin Channel Class A/B amplifier. All valve, 50 watt RMS, channel-switching head with foot switchable attenuator, valve FX loop and valve-driven reverb. This amplifier sports two clean/crunch lead channels, each with three stages of gain. Channel A has the same three band EQ as the lead channel used on the Rockerverb series. Channel B has a new shape control that scoops the mids and decreases the bass and treble when turned up. Use this scoop knob to dial in everything from vintage rock to modern blues, hard rock to metal.
The Thunderverb 50 also has a foot switchable attenuator. Dial in your rhythm tone at a lower volume, then activate the attenuator to boost the volume for really loud breaks, all without affecting your tone!
If you like the tone of the Thunderverb 200, but prefer the sound of a smaller cranked 50 watt power amp, then this is amp for you.
