I put a pair of WGS Retro 30's in my Roadster Combo a couple of weeks ago. Very quickly the speakers seemed to settle in and sound exactly how I'd always wanted the V30's to sound.
So I ordered a quad of Retro 30's from NextGenGuitars.ca for my Deliverance 4x12. The stock P50E's sound amazing with my Fryette amp, but "meh" with anything else I own (I think they're designed for a much higher-Gain style than mine,) and I really want a do-everything Rock 'n' Roll cab, so out they went and in went the WGS.
Awesome! Again it only took an hour or two for the Retros to break in enough for me to like them a lot. I was worried they might be too bass-y in there, but they're not - everything's just right. I can dial in as much bass as I can stomach without it becoming boxy or boomy, and the highs are just right (which is why I didn't go with the Veteran 30's - a bit too dull for my old ears) where I can still use my Presence knob to good effect even with my Treble set low (which is a super important feature for me.)
Now my Deliverance cab is a total Rock machine! Equally good with my Fryette, Rivera, and Mesa. Better Cleans than the P50E's.
Now I'm off to break them in even more!
