If you're looking for a classic Rangemaster-based treble booster built with proper NOS or reclaimed audio components (this one sports a Philips/Mullard AC107) then you need to check out Van Diemens Effects Red Ochre Deluxe. As well the classic Dallas voicing (although slightly less spiky) there are two other modes - mids and lows - on tap as well. It's built with integrity, skill and passion as well as a welcome waste-not-want-not ethos that drives the recyclable and reclaimable philosophy behind all of Richard Turner's work. Classics with a conscience. I like the sound of that and I love the sound of the Red Ochre Deluxe.
