I had a HRD for several years. Great clean tone and it does take pedals well, but any tube amp is going to color the tone of your acoustic guitar. If you are good with that the HRD is a really good amp and you may be able to find one for $400. I switched to a smaller Blues JR because I wanted something lighter for hauling around to jams and gigs.
I often play my Acoustic through a PA and run it through my multi efx pedal where I have a volume pedal, distortion, delay, etc... Electric effects work fine with an electric acoustic. Go to youtube and listen to Rob Butler Trio.
Have you thought about getting a small PA instead of an amp?

Can you turn the reverb off and use a good reverb pedal instead? Probably cheaper than other options.
