gibson es 335 blue

Should i sell my Gibson ES 333 (different from the 335…cheaper. Around 1200) and buy a G&L S-500?
The 333 is a discontinued guitar from Gibson…it is similar to a 335.
I play rock, blues, jazz and some prog rock stuff.
Also i have a Fender Twin Reverb
That’s a tough call. A REALLY tough call. As much as I’m a fan of the strat (G&L’s too), I’d have to say that big boxy Gibson probably sounds great playing the blues and jazz. The G&L would be versatile enough to do all 4 types of sound that you mention, but I personally would have a hard time getting rid of something with as much character as your ES 333 only to replace it with a G&L strat copy (not nearly as much character in my opinion).
Nice amp too!
Good luck with that debacle (keep the Gibson and get a Fender American Standard Strat–that’s a good compromise eh?)
