The RPA Major is the answer to many customer calls, demanding the hard, agressive Ritchie Blackmore stage sound of the 70's, without the need to get their amp heavily modified. The RPA Major offers a lot more gain compared to the stock RPA model with tons of crunch and a higher level of agressivity ... something that fits the modern Metal scene as well. With the level control turned up to the max, the RPA Major delivers an output level of 8 volts (!!!), which can kill most modulation stompboxes with electronical CMOS switching like delay, chorus etc. that are connected after the RPA Major in the signal chain. So please only use the RPA Major with full level directly into your tube amp. If you want to connect some stompboxes after the RPA Major, reduce the level to 50% to be on the safe side.

RPA Major special Booster

In 1974, right before the start of the "Burn" tour, Ritchie Blackmore changed his live setup. First and foremost, he wanted to play live with an echo effect and made the AIWA TP-1011 reel-to-reel tape recorder his first choice. This unit offered the typical 1/3 seconds echo repeat, perfectly matching Blackmores natural beat. Additionally, Ritchie Blackmore used the integrated microphone pre-amp as a booster, and with this his beloved Hornby-Skewes treblebooster he used for many years was not longer needed and was sent into retirement.

RPA California Treble Booster

The BSM RMG model is based on the british Vox Treble & Bass booster made in the late 60's, used by many british bands at this time. Here is a custom version of this Vox unit as a homage to the famous BYRDS guitarist Roger McGuinn and his signature "jingle jangle" sound. The RMG´s customized tone network, makes it the perfect treble booster for all clean sounds. The RMG model includes a tone control, that allows an extraordinary amount of versatility. It can add a lot of twang and spank to any guitar sound. By pronouncing the percussive attack in a very musical way, any guitar will sound more "in the face" that way.

RMG Treble Booster Jingle Jangle Machine

Brian May from Queen used in his early days the British Range Master Germanium Treble Booster, a unit produced between 1965 and 1969. This model is rebuild as RM by BSM. In mid-phase from Queen, BrianMay switched to a silicon Treble Booster design for more bite, now reproduced by BSM with orginal silicon transistor and called BM-Q special. The same unit fitted with volume control called BM-Q.

 BM-Q special Treble Booster 

The Hornby-Skewes Treble Booster was Ritchies favorite box for live and studio recordings like the famous 1971 "Machine Head" or the later 1974 "Burn" session. The HS-S Master in front of a Vox AC30 gives you the unique sound of the well-known rock hymn "Smoke on the water". Compared to its forerunner, the HS-S sounds a tad more aggressive with more mid-range with the guitar’s volume pot fully opened, a little bit similar to a WahWah sound. But the higher the pre-amp volume of the amp is dialed in, the more this midrangy tone will be forced into the background because now the saturation of the amp will generate the necessary harmonics. So it´s up to you to chase the sweet spot of the HS-S unit. You will have to raise the pre-amp volume of a Marshall Major noticeably because this amp is a very clean sounding one. To have some good reserves when dialing in the pre-amp volume Blackmore had his Major amps modded early with a cascaded pre-amp design right from the factory.
