Außer zum Hornby Skewes griff Ritchie Blackmore Anfang der 70er Jahre auch noch zu einem weiteren Booster: Dieser von Bill Hough für ihn entwickelte und gebaute CM Booster liefert den Basissound für den 71/73.

Mit seinem Mode Regler blendet man die spezifischen Charakteristika des Hornby Skewes Boosters mit Germanium Transistor (HS-C) oder mit Silikon Transistor (HS-S) mit dem des zugrundeliegenden CM Modells von Bill Hough. Der Bright Regler steuert Höhen und Gain.

Dieses Modell kann auch allen Humbucker Usern empfohlen werden, die ihren Sound heller und knuspriger haben wollen, da er als nicht zu starker Booster sehr gut zu Humbuckern passt.

Mit einem AC30 lohnt der Einstieg mit einem Standard Setting: Bright auf 8 Uhr, Mode auf 2 Uhr im Normal Kanal - nicht im Brilliant Kanal. Achtung: aus technischen Gründen funktioniert der Bright Regler entgegend dem Uhrzeigersinn!

Leichter Boost-Effekt.  Deutliche Lautstärkeanhebung. 100% True Bypass

Idealerweise sitzt der 71/73 innerhalb der Signalkette direkt hinter der Gitarre (Ausnahme Wah-Wah)

Der magische Sound des Boosters entsteht durch die Interaktion zwischen Gitarren Pickup, Booster und Röhrenvorstufe. 

Verarbeitet werden ausschließlich strengst selektierte Germanium und Silizium Transistoren aus alten Original-Beständen NOS!

From 1971 forward, Ritchie Blackmore not only used the mid-rangy sounding Hornby-Skewes trebleboosters, he also used the highly dynamical and brilliant sounding CM booster, built and designed by Bill Hough. The new BSM 71/73 CM is a faithful recreation of this pedal plus the typical BSM add-ons. This is all you need to cover the whole tonal range of the legendary Deep Purple Mk2 period. The "Mode" and "Bright" controls make this low-gain stompbox extremely versatile, producing a classical Hardrock tone with a lot of nuances. Not only useful for Blackmore-sounds this is a pedal that also works well with humbucking pickups, giving you a crisp yet dirty crunch sound on an already overdriven tube amp. You will even get a super-clean funky tone with single coils and a clean amp. You will probably never want to switch off this pedal anymore.

Setting advice for BSM 71/73 CM Booster: Standard setting for the 71/73 CM bases on the 1971 CM (custom made) booster built for Ritchie by Bill Hugh and should be used in front of a normal amp without an additional bright-enhancement circuit: "Bright" at 8:00 o'clock, "Mode" at 02:00 The "Bright"-control of the booster works similar to the bright volume of an amp. For technical reason the direction of the controller works contrary to the common direction counter clockwise. This means, that the noticeable full gain-setting without bright-enhancement is at minimum 7:00 o'clock (full left). Maximum treble (or better maximum bass-mid-reduction) can be achieved by turning it up full at 17:00 o'clock. At 9:00 the booster works with a little reduced gain and barely noticeable treble-lift, thus can be defined as neutral. In between 7:00 and 9:00 the gain-range can be described as sound-neutral. For Ritchie's airy sound around 1971 and 73 it is not necessary to use full gain. 9:00 is good standard setting to start with. The "Mode"-control provides the specific frequency-range of the basic-booster model what is the CM-booster by Bill Hough, generating Ritchie's 71 Beat Club sound. Around 1973 Ritchie additionally started to use his new Marshall Majors with the bright-volume-characteristic. Therefore to generate his 73NY-sound it is necessary to turn the Bright-control to about 13:30. Fine-tuning around this point belongs to your personal taste and equipment. By turning the Mode-control less or equal 12:00 and Bright to about 8:00 means entering the area of the old Hornby-Skewes-boosters. To emulate the germanium fitted HS-C booster you will have to turn Mode to 12:00, Bright 8:00. The silicon powered HS-S can be achieved by turning the Mode fully back to 7:00. In most cases it will be useful to give a full gain setting on the bright-control. Just to remember: the pot works counter clockwise, therefore the position is 7:00 To achieve a nice power-boost set Bright to full gain at 7:00 and Mode to 12:30 to 13:30. This way low gain single coils can sound like the fatter Quarterpounds. If the sound should be most biting, Mode needs to be at least 15:00. Ratio between treble and bass can now be balanced via the Bright-pot. This should be set greater than 9:00 to have a tight and clear bass, not to overlie the brilliant treble. The higher the Bright-control-setting, the cleaner and slender the bass will be.
