1995FX - Stomach Ache

Mr. Takamatsu of The Novembers Prodice 1995fx Stomach ache [You can try the sample machine] 
It is recommended not only as a bass preamp / booster but also for a guitar !! 
Producer's comment 
"With four controls called Volume / Saturation / Dull / Sharp It is a Deep Switch. 
Volume, as the name implies, is for volume control and can also be used as a buffer by maximizing Volume and minimizing other controls. 
Saturation is a control that gives a sense of saturation, and by raising it, the midrange also comes out slightly. 
Dull is a control that boosts low to ultra low frequencies, and you can control the lower band by tilting the Deep Switch down. 
Sharp can control the mid to high range and can emphasize the outline. 
Produced by Mr. Takamatsu, this work is recommended for bass, but it is also very suitable for guitar, and it is very compatible when playing arpeggios cleanly. Also, according to springman (PAM / Tricondor) who is in charge of the web etc. of 1995fx, he seems to like that the sound of the line through DI with Dull and Sharp set to full ten has the texture through Ampeg. is.
