Oh dear...
Went in to PMT Southend, paid for three hours parking and wandered into the shop expecting a lengthy, soul searching wrangle with the issue of going over to the RnR killing dark side that is an FRFR setup. The excellent staff there set up a QSC K12.2, set it to the bass amp preset, I plugged my bass into my Fishman Platinum, set everything at 12 O/C so I had the flattest sound possible and started playing. It took twelve minutes to see the light fully and six of those were just waiting for the assistant to return.
So I am putting two basses and my AER Basic Performer up for sale and as soon as I've shifted the AER this will be my new setup...
...I didn't have to discuss anything with the shop assistant, I was fully prepared and armed with all the possible info, how simple it actually is to make the right decision when you have a huge 38 page thread like this that does all the arguing and comparison for you, all one has to do is go in, try it out and confirm it. This is exactly what makes Basschat a massively useful and important resource for its members.
