Probably calling out mostly to the Australianas. A friend of mine turned me onto these after he bought a BWM Kong- 5 watt head, with one 6L6 and said he got some of the best sounds ever out of it. Recently got myself a Silverback head, Princeton clone $480 Aust. Two channels- blackface princeton with same controls (no reverb though), flick the boost switch for Brownface Princeton- bypasses the tone stack, more gain, very responsive to pick attack, beautiful clean sound, pristine sparkly tone even at extremely low volumes. Out of the box without tweaking anything this thing sounded beautiful. It was in the Brownface mode, with the volume almost all the way down. Plugged in a tele with broadcaster bridge, and it produced thick sparkly tone, no pissy weak or tinny sounds, just full and luscious. Using it through a 1x12 with an eminence swamp thang and diggin it. Amy other BWM fans out there?
