I'm young on the keys and even I know that the A100/B3/C3 is the way to go. Nothing wrong with a C2 tho'.
IF IT DOESN'T SAY HAMMOND, TAKE IT BACK TO THE STORE. PERIOD
IF YOU DON'T HAVE A LESLIE, GO GET ONE. PERIOD
IF IT'S NOT A HAMMOND AND YOU THINK IT SOUNDS GOOD, GO GET YOUR EARS CHECKED.
AND IF YOU REFUSE TO COMPLY YOUR ORGAN PASS WILL BE REVOKED. AND WE WILL ASK QUESTIONS LATER.
Seriously though.....Don't let nobody visit your church and see an Organ that says something other than HAMMOND.
