Title: How can I change the eq point of the mids, 18 watt TMB-MV? Post by: boogieguy on December 10, 2008, 02:22:22 PM I'm a newbie and just built an 18 watt TMB-MV (non EF86) with Heyboer trannies. I would like to have a little more low mids from the tonestack. What do I need to do to change the center frequency?

Post by: M Fowler on January 01, 2009, 06:56:19 AM Try a lower value capacitor off of the mid control. Also you can change that mid control from what you have a 22K, 25K to 50K, 100K, 500K or even 1meg.
The mid control wasn't used on many old amps a capacitor is use only by adding the pot you have a variable mid frequency control. |
