I have 5 ACGs at the moment, I think I've owned another 5 or 6 over the years. I have two 33" 6ers, a 34" 9 string, a 24" 6 string and a 7 string headless guitar. All are fantastic beasts. The 34" 9 is absolutely crystal clear across the strings - the glassy clarity of the treble strings really makes for a writers instrument. The two 33" 6ers are both Salace E-Type basses - my personal favourite body shape by far for looks and ergonomics. The Bs are perfectly useable, I'd suggest buying the ACG specific 33" Newtone Strings. The 24" 6er does suffer a little bit when played unplugged in terms of feel and sound because of the much shorter scale, but still sounds massive plugged in. For context, I've owned at least one of almost all known bass brands over the years from the cheap to the highest end boutique basses money can buy and ACG (as well as Conklin, BeeBasses and Warwick) are the ones I always come back to and certainly the ones I have owned the most of! It helps that Alan is a great guy to order a custom bass from, plenty of regular communication, questions answered very quickly and photos sent all along the journey. Sound wise, the below song was recorded with a 33" ACG Salace E-Type 6 string.

This is the 9 string (when I was 7 stone heavier!)
This is a Salace 6 33" (a very quick demo):
And this is the 7 string guitar a few years ago with me just noodling about:
Hope that helps! Happy to answer and questions should you have any.
