Lehle RMI Basswitch Classic Boost · Bass Guitar Effect

During the fine tuning of the Basswitch Classic Boost were classically passive P-, JJ- and PJ bass guitars in mind. This compact preamp connects the boost function of Basswitch IQ DI with a specifically tuned 3-band EQ for vintage basses . In addition, the level controller acts with damping as a passive tone control and as an active regulator when it lifts.
By Basswitch Classic Boost the installation of active electronics on the instrument is unnecessary, which obviously pleases collectors and enthusiasts then having more originality in their instruments and the sound of vintage bass gets a new tonal splendor, without changing the characteristic sound of the instrument.
The Basswitch Classic Boost has a controllable gain by +/- 15 dB and can be used on an active monitor or speaker cabinet as a standalone booster, as an extension to Basswitch IQ DI or as a compact standalone preamp.
The proven Lehle True Sound Technology provides the Basswitch Classic Boost with the right tone: Starting on the discrete JFET-input stage switching via gold-plated relays provides this booster with a more than studio-grade dynamic range of over 110 dB with very low noise. The Basswitch Classic Boost works internally with 18V, but happy nonetheless with all power supplies from 9 to 15V AC or DC. The extremely robust construction with protected controllers and virtually indestructible switching mechanism provide many years of fun with its classical boosting!
