This ad sells aluminum knobs for Roland TR-6S
we manufacture and sell accessories for musical equipment. In this announcement we are introducing anodized aluminum knobs for musical equipment: samplers, drum machines, midi controllers.
With many knob purchases we try to include hex keys as a gift to secure these knobs, but this may not always happen because these keys often run out.
