Treble Booster BSM RPA-Major
The special treble booster BSM RPA-Major is very good for the aggressive 1976-1978 Rainbow live sound.
It is a hot-rodded version of the normal BSM RPA with more gain.
The Sound is near to Ritchie Blackmores Equipment. The Booster simulates the AIWA TP-1011 reel-to-reel tape recorder with the typical 2/3 seconds echo repeat.
to perfectly match Blackmores natural beat.
Its not only rebuild the AIWA preamp stage, but also integrate the important highpass function with the original cutoff frequency.
The RPA Major is equipped with a gain control. The EQ control allows a tonal fine tuning for the use of the RPA Major with different pickups, amps and speakers.
