Your guitar pickup wants to see a vacuum tube before it sees anything. Let alone a chain of stomp boxes, the inherent array of capacitive loading cables & connections in the signal path.
The VTLD 1 Vacuum Tube Loop Driver restores dynamic touch response and tone integrity via two custom tailored tube stages: A 12AY7 receives your guitar pickup and conditions it to drive your stomp pedals. A 12AT7 recover stage sends your post effects optimized signal on to your amplifier input.
Plus – a sublime vacuum tube GAIN BOOST stage with independent level and tone control, LOOP BYPASS and a discreet MUTE/TUNE output.
