Bias Mod Example: Mesa Boogie MK-III
Below, the MESA BOOGIE MK-III BIAS MOD: 2 Bias Pots installed
1 bias pot for each tube pair. The customer wanted to have access to the pots from outside the chassis and we both found a good spot underneath the speaker jacks.
This amp can now run a great variety of tubes, different tube types, different brands. Plus, they can be biased HOT or COLD !
We installed 4 bias pots (1 for each tube pair) allowing use of different power tube types. This customer wanted 4xKT77 on side A and 4x6L6 on side B.
Now any tube type and brand can be installed and biased.
Now any tube type and brand can be installed and biased.
Channel 1 had lost it's tone, no bottom end, dull sounding and tone controls not working effectively. After overhauling this channel it sounded great again and customer was thrilled !
Original EQ had developed a loose contact with 2 of the sliders resulting in severe volume loss. We had Mesa make a brand new EQ.
