Okay folks. I'm hoping Mr. Goodsell will chime in here but if not I still need some advice. I have previously asked a question or 2 about my Goodsell amp on this forum a few months ago. To me, My amp sounds fizzy and not as nearly as sweet as other Goodsell's I have heard. I bought this amp online just because it was A Goodsell -- without ever even hearing it. I have tried and tried to get a nice sound out of this but I just cant seem to get there. Its okay but I know it can be better. My amp is the Goodsell 17 with 2x10 speakers (signed by Richard on 12/16/16). It has 3 knobs, Gain, Tone, and Volume (no reverb and no tremolo). It has 5 tubes: 2 12ax7's, 2 el84's and a Rectifier. I have swapped out the EH pre-amp tubes (I guess they are both pre-amp tubes, i never could get confirmation from the man) with some tubes I retrieved from an old Fender Showman Blackface head (I'm not sure what they are -- i can just make out the 12ax7 label but i see no manufacturer's name). I really could not tell much of a difference. I purchased the rectifier tubes Mr Goodsell talks about on his video Blogs. I tried both the 5y3 (is that the correct number?) and the long one. I really did not notice much of a difference. Maybe a bit of an improvement using the 5y3, but not much. So now I'm looking at the speakers. According to Mr. Goodsell, the speakers I have aint the ones that came with it. It has an Eminence 1028 and a 1058. If I am not mistaken, Mr Goodsell said it originally had a Ragin Cajun and a Copperhead, both Eminence speakers. I have always been partial to Ceramic and not Alnico mags. So, with that said, I am looking at using maybe a Celestion Vintage 30watt or a Greenback. Okay, here's my question(s): Should I go with the Celestions or should get the speakers that originally came in this amp (Ragin Cajun and a Copperhead)? or should I go with something else? I play mainly late 60's early 70's style Rock and blues. There's a 10" Celestion ?Vintage? at Guitar center for around $38. The price suggests a cheap, made in China Speaker. Wondrer how it sounds? I am open for any and all suggestions. Thank you all!
