I don’t personally care for Country music per se, but I just LOVE that guitar tone. I run an American Deluxe Tele (as well a Les Paul and Godin LGX) through a ’65 Deluxe Reverb Reissue and get that beautiful Fender sparkling clean tone. With the Tele the tone I get is what I affectionately refer to as “Country Sparkle,” and I mean that in a good way. The Godin LGX has Piezo pickups (for fake acoustic tones) and it sounds great through the Deluxe Reverb. The amp is a bit heavy at 42 lbs. so I installed a set of Ernie Ball amp casters on mine to make it easier to move around.
To get what I think of as the “Nashville” sound I put the Boss CS-3 Compression/Sustainer in front it. For that perfect “Country Crunch” sound I use the Boss BD-2 Blues Driver. Run the compressor and overdrive together and you are in tone heaven for Country or Blues. Add a digital delay such as the Boss DD-6 for some good slap-back echo. Get a pedal board from www.nycpedalboards.com
to hold the pedals and make for easy transport.
If the Deluxe Reverb is too clean for your daughter’s taste, then as recommended by others try the Hot Rod Deluxe or Blues Deluxe. I personally prefer the Blues Deluxe. They are both a bit heavier at 45 lbs. and have the potential to be much louder than the Deluxe Reverb. A Blues Junior at 31 lbs. could be nice choice, but it may not have enough power for a live setting. However, these are probably not as nice for acoustic as the Deluxe Reverb or as another post mentioned the Roland JC-120.
Hope that helps!
