I sent the full range out to the return of my Mesa Boogie Walkabout head to test it out. However the the volume is much lower that it should be. So I put a jumper cable between the send and return sockets of the F1-x and the volume went up to what I think it should be. i.e. loud. When I take the jumper cable out the volume is down really low. Is it ok for me to leave the jumper cable in and use it on a gig? Previously this preamp was used in the bridge pickup for my series basses and had a channel of my SF-2 going patched into the send and return and never noticed a problem. Could it just be a jack exercising problem or something else? keith_h Senior Member Username: keith_h Post Number: 2392 Registered: 2-2005 Posted on Thursday, March 31, 2016 - 3:16 pm:    Sounds like the jack contacts are oxidized and need exercising. When nothing is in the jack the signal goes through the contacts in the jack and can see problems due to oxidation. When you put in a jumper cable or go to the SF-2 the signal no longer goes through the switch contacts and instead goes through the cable.

Mica sent me this link a while back after I had a similar issue with my F-1X. http://alembic.com/club/messages/16271/16301.html?1107539284 ps - +1 on F-1X's full-range out to Walkabout return... that's a magical sound. It's what convinced me to finally build a pre-amp/power-amp setup. jazzyvee Senior Member Username: jazzyvee Post Number: 4971 Registered: 6-2002 Posted on Friday, April 01, 2016 - 7:02 am:    Ok thanks I will try that when I get round to practice later. yeah that mesa boogie in that mode is meaty and thick and even though the F1-x has less knobs it sounds much more powerful and clean than using the boogie front end.
