Good news for all Ritchie Blackmore fans. The high output level of his treble-booster often causes problems with the following modulation-unit, especially with the echo-unit that is necessary and important for the real post 74´ Blackmore sound. BSM solved this problem with the brandnew RB box (aka Ritchie´s box ?!?), a pure passive looper with two special line-transformers, designed with the help of LEHLE Guitartech. In the first step the input level is lowered to approx. 50% to have the standard level for overdrive-free processing in other effects. In the second step the signal is pushed up again to 100% in the Return-Section up to the original output-level. With this tricky thing it´s also possible to combine today's modelling-effects and old-style treble-boosters ! The RB box works absolutely passive while the top-notch transformers will add those analog flair of Ritchies AIWA to all digital echo- and delay machines (recommended: Boss DD-3). With some tricky backward-wiring you can also use the transformers to push any connected stompbox (eg. an overdrive) to twice or fourth of it´s original output to reach the output level of a treble-booster with the benefit of it´s mild and soft characteristics.
