We just got in our shipment of Pete Cornish TB-83 Treble Boosters. The TB-83 was a crucial element to Brian's sound and when used with the pickup selections on the Red Special, you can get a wide variety of tones.
You can call us at 415-957-9131 if you have more questions.
I also have the Morley George Lynch Tripler that has a boost knob so that you can split your signal three ways.
p.s. I'm going to have REALLY exciting news in the next few weeks regarding Brian May Guitars at Audio Images. Stay tuned.
