The T-Rex Fuel Tank Junior JUST fits underneath a Nano or Mini without having to make any cuts into the pedal board.
The first problem is the widththe front to back spacing between the bottom lengthwise frame on the Nano
or the bottom lengthwise frame and the lengthwise spar/brace on the Mini.
As you can see from the pics, the FT Jr. just fits and in fact according to those who have done it, the FT Jr. wedges in tight enough the you may not need to use any other means (Velcro, etc.) of holding it in place. I havent done it, so all I can say to that is YMMV.
The second issue is height. The FT Jr. JUST BARELY clears the ground when the board is placed on the floor in position. Many people choose to raise the board up by extending the feet one way or another (drill out the rivets and place new, taller feet in or find taller rubber feet that will fit over the existing feet.)
From these two issues you can see that most of the other power supplies simply wont fit underneath a Nano or Mini unless you modify the board (cut away some of the metal). This can and has been done (a google search will bring up examples).
As far as powering your proposed pedals with the FT Jr, you should be fine.
The FT Jr will power the Diamond with a serial cable, the double end of which is plugged into two of the FT Jr outputs and the other (single) into the Diamond.
If you choose an Aguilar Tone Hammer as your preamp/eq/di, use Aguilars power chord (
Link Removed), which can also be located underneath the Nano/Mini. So, youd be dealing with 2 power chords, one from the FT Jr, and one from the Tone Hammer power chord. Not really a problem.
The other 3 pedals get their own cable from the other 3 FT Jr outputs.
and youre good to go!
