OK..I have been playing my Ibanez btb405 for a few years. I play through a Fender BassMan 200. I play at church and it just can't keep up with the other musicians. I have it at max and my bass at max. Last night I brought a Hartke LHA5500 and a HARTKE 4X10 cabinet. I would like to continue to use the BASSMAN for the 15" woofer. Is it OK to take the send out the HARTKE and run it to the return of the BASSMAN? Will this hurt anything? Any advice would be greatly appreciated. First post please be gentle.
