B.K. BUTLER TUBE DRIVER CORNISH MOD

For Sale: B.K. Tube Driver

Factory model featuring Bias adjustment and a NOS Yugoslavian 12AX7 tube.

Professionally modified by REDSEVEN AMPLIFICATION with the following Cornish-inspired specifications:

• Input and output buffers, similar to those used in the Cornish LD-1 Line Driver, designed to lower output impedance and make the pedal more transparent and fully compatible with the rest of your effects chain, eliminating interfacing issues.
• Power supply conversion to accept standard external 9V power supplies, with automatic internal rectification up to 30V. This modification drastically reduces hum and background noise while improving dynamic response.

After the mod the TD has become a better pedal with less noise and fuzzy, great dynamic and headroom, tight and focused bass frequencies.

Condition: Perfect working condition.
There are a few cosmetic marks on the exterior, clearly visible in the photos.

The pedal also comes with a TAD 7025 S Premium Selected tube, a reproduction of the legendary Mullard ECC83, produced in the 1960s. This tube is included for those who prefer a smoother, warmer tone compared to the more aggressive character of the original Yugoslavian NOS tube.
