Some pieces of British musical heritage, two authentic and one replica. A vintage Vox AC30/6 and a newly acquired Vintage Pedal Workshop (VPW) Dallas Rangemaster replica treble booster hand built by Steve Giles. This is one of the best and was based on an exact replica of the yellow jacket Mullard OC44 transistor. It sounds fantastic. A new old stock (NOS) vintage Mullard GZ34 full wave rectifier valve destined for my 2000 Vox AC30/6 TB.
