Title: New Hey What?! 504 OL? Post by: NowhereMan07 on February 14, 2010, 08:40:44 AM So, I logged onto my favorite amp builder's site today and noticed a new Hey What model! Being very intrigued by HiWatts, (not to mention saving up for my first Ceriatone) I was wondering if anyone can provide any info on this new model? Thanks!

Biacrown's "high gain" model moved back to the Input 1 circuit (still keeping PI 2), but used the "extra" half triode as an additional gain stage. Title: Re: New Hey What?! 504 OL?

I asked Nik about it the other day and he said they've now got a knob on one of the inputs to control the gain, so if you want to tone it down for old school HiWatt clean, you just pull it back. It's also got a bridged input. Can't wait!
