Lehle Dual A/B Switch Box

Used Dual A/B from Lehle in very good/excellent condition, pedal only as we do not have the original packaging or PSU.

About the Dual A/B:

The Lehle Dual enables you to switch between 2 amps or run your signal to both amps. The signal is routed directly (without semiconductors) via gold-plated relays to Output A or B or both. A is electrically isolated from B by means of a high-end (Lundahl) line splitter; humming loops are impossible, even if A and B are switched on simultaneously. The Lehle Dual can use any power supply between 8 and 20V with either polarity (AC or DC). The supply voltage is internally rectified and stabilized in order to guarantee trouble free operation. High-intensity LEDs behind a magnifying lens make it easy to read switching state (A and/or B) even under bright spotlights. External trim potentiometers make it possible to adjust Output A or B if both are engaged simultaneously. For example, gain (up to 6dB) can be trimmed back so that one amp gets hit harder than the other. All Lehle switchers are totally passive. To the purist, what this means is that the great tone you bought your particular tube amp for in the first place will not be compromised. Active switcher boxes (with their resultant change in impedance from high to low) cause an amp's crunch/distorted tone to become fuzzy. Lehle switchers maintain that unique interaction between guitar and amp, as if there is only a high-quality cable in-between. Features
