DBX is good compression. However, an effects pedal type compressor might be more tailored for a guitar. The compressor is part of the rock n roll sound, i suppose. Makes you sound better than you actually are. It works for me like in the video.
The Gretsch? $620 Brand New with hardcase. I will never figure out how guitar buying works. It came as described. Currently the' Buy it now' is $699. For a $999.99 guitar. I don't get it. Hundreds cheaper than the big chain stores.
