The guitar amplifier. It is a big element of guitar sound. In the era when the guitar was a musical instrument that did not take lead even in the big band, the guitar amp may have been good if not even distorted.

When the guitar established the position as a lead musical instrument, as the performance on the big stage increased, the output of the guitar amp increased as we asked for a bigger sound.

The distortion of the amp became recognized as a good sound rather than noise, and more guitar amps were made by seeking more versatile distortion and tone.

When the PA system became common and the sound from the amplifier does not need to be delivered directly to all of them on a big stage, further amplifiers are fragmented. A vast variety of guitar amps have been produced in accordance with the required timbre, characteristics, quick response and so on.

Guitar amp to be produced in full order according to the sound demanded by customers. Among others, there are amps to be told with an overwhelming legend. Dumble. "Overdrive Special" "Steel String Singer" Although there are model names, everything is custom made. Not to mention that one unit is different, the players who have plugged in guitar even to one of them are limited in the first place.

Therefore, what is told as "Dumble sound" is often the sound of prominent artists who are its users. Because many of them are blues players, the sound called "dumbling system" is a high response and the low midish sound is heavy. Although it is certainly excellent as a lead of blues and fusion, it is surprisingly difficult to use.

There's a limited amount of players who have the opportunity to play a real Dumble, but there are those who touched more Dumbles than the owner and know the real Dumble. Given that the tube amp needs regular repair, the answer will be obvious. Indeed, especially if it is a damper amp built on the basis of the finest vintage fender amplifier.

One Control Golden Acorn OverDrive Special developer BJF says that he played a number of Dumble Amps with a "best friend" who knew of the Dumble Amplifier. The essence of Dumble is "custom made for artists", there is no "Dumble sound" in the true sense. That is BJF's view.

On the other hand, there are certain characteristics and characteristics common to all the Dumble amplifiers, BJF continues. The greatest feature is that it is a dynamic range.

Golden Acorn OverDrive Special is a Dumble Amplifier in a Box that captures the features common to Dumbles. It is staggeringly made with a structure close to the black face pedal, Sonic Blue Twanger, which surprised the world. Many of "real things" are based on vintage black face.

You can control from clear to clean to heavy gain by touching. Moreover, the distorted sound with a strong attack will not drown out other sounds. In other words, chord separation is good, yet it will be uniform and coherent sound. Sounds do not fall apart, yet they are not cloudy. The gain range is wide, but always creates a clear sounding.


The Golden Acorn OverDrive Special RATIO knob is the basic gain control. If you are humbucker, please start this sound at 11 o'clock with this knob and 12 to 1 o'clock in the case of a single coil.

Golden Acorn OverDrive Special (GAOD) has the features of many of the Dumble Amps I have played so far. When using GAOD, I would like to propose to install as much as possible at the beginning of the pedal chain, especially before the compressor so that this dynamic range can be utilized to the maximum extent.

It will be "spade" which controls the dynamics range in the pedalboard.
