拘りの音と性能の高さで知る人ぞ知る、ハンドメイド ブティックペダルブランド’Blackberry JAM’ の工房です。

"Mure" is the Dumble amplifier system overdrive of multiple functions equipped with 3BAND EQ.
"The particular strong sound is made easy to use" , it was born by the theme I say.
All EQ parts are active control, and will cut the way with left turning as a flat at 12:00, and is a boost by right turning. It's possible to set the middle as wide range from the low middle to the high middle in particular.
Perfect clean tone can be made in the state with which the gain has been broken off, so you can enjoy a done bull sound until I come to the big volume from the small volume as a preamplifier-like model based on a clean boost.
A legend-like sound of a vintage amplifier, a wide microwave.
It outputs completely by high resolution and the high response.
