Ceriatone OTS Custom + Dumbleator Custom Rack + Custom Wood Rack - 25W/50W

Ceriatone Overtone Special 25/50
w/ Custom Made Dumbleator + Custom Made Wood Rack Enclosure + Power conditioner + Footswitch.

Built around 2010 Pretty straight ahead from the Ceriatone schematic.
- The outboard device in the Furman chassis is a “Dumbleator”, essentially a preamp that adds gain between the preamp and power amp.
- Dumble designed it so people could use rack effects like delays and compression, it makes the FX loop active instead of passive. Without it there’s not enough signal in the loop for that stuff. These amps were originally designed in the 60’s, way before there were effects processors for guitar rigs.
- The RF-Choke switch subs a resistor for the power supply choke, it increases the sag a bit.
- RF stands for Robben Ford. His Dumble has a resistor instead of a choke on the output of the power supply. A choke is typical, it stiffens up the power amp, using a resistor instead allows for more sag. You will only hear/feel it when the amp is right at clipping tho, very loud.

Fun fact- the six openings in the panel right below the amp were cut using a Strat pickguard as a template.

I am happy to video call the buyer and send a copy of my ID prior to payment.
