Why does it need to be swamped in reverb?
Probably because the guy liked it and thought it sounded good, ya know like Eddie does. Like that very famous Kemper Golub Crunch mod Marshall clip where the guy uses a Strymon Blue Sky and a little Brute drive and Kemper reverb and ambience. Why not the just Kemper on board effects? Because it sounded good. Dean's Bogner clip has a bunch of delay, works for me. In all 3 clips, Deans, the Golub, and that random Axe Bogner, I can still hear the tones and to my ear, they are all just dandy with the Golub leading the pack.
Probably one of the best amp tones ever in that.
I didn't think posting a clip here would go over well at all. Kinda like eating a bacon sandwich in a Mosque. I just thought that clip Dean put up of the Axe Bogner was a bad clip.
