BSM Spice Box
The BSM "Spice Box" is a faithful replica of the old MTC filter box for guitar installation used by Ritchie Blackmore since around 1978, now using modern selected parts because only the best is good enough. The treble bleed function is intended to clean up the tone with a tighter bass response, when the volume control is rolled back. Ritchie used this volume setting for soulful soloing as well. In order to get a sweet sound with this setting, the second feature of the BSM "Spice Box" was incorporated: a mid-filter, using a toroidal-coil with selected core. Compared to a standard tone control, the mid-filter creates more chime and high-end, resulting in a warm and sweet tone, but with a good portion of transparency to prevent it from getting muddy - one of the real secrets of the BSM "Spice Box" ! With the volume rolled back, Ritchie often used the MTC´s mid-filter function to sweeten up his tone when needed. You can put it under the tone pots of most standard routed Stratocasters.
