Find a used Soldano HR50+ or HR50 or avenger. They would be in your price range, and Soldano tone is pure liquid harmonic mojo. You really need to hear a Soldano before making a final choice if you want smooth. I had an HR50+, and it was smooth! I only sold it to get my SLO, which I'll have for life. You cannot got wrong with a Soldano if you want smooth hi gain overdrive dripping with harmonics and three dimensional liquid tone...!!!!
