eTap2 VST is available in two flavours. The first build is what most people are using. The build 2 also available from my site is with an addition that makes the guitar stands-out in stereo more like its done by Peter Korving. The adjustments are more complex.
There is a 3e version upcoming that includes also reverb. The availbility is presently scheduled behind the eTap2hw activities. (eTap2hw is the hardware version available as a DIY kit).
There are no plans yet for a 64bit version although a new compiler seems to support that. I need to look into that when time permits. The standard compiler was updated a couple of months ago so all is intentional
