The Udo Rosner Hash consists of
- An undersaddle pickup
- An internally mounted microphone
- Controls mounted inside the soundhole
- Socket which can double as a strap post.
Connecting – don’t forget to turn the volume control on your amp to 0 before plugging the lead into the guitar and amp (otherwise you get a loud “pop” from the speaker).
Controls – The controls are located inside the soundhole on the bass side. The rotary control nearest the bridge is the master volume output for both pickup and microphone. The rotary control nearest the fingerboard is the blend control for the mic.
Battery – the 9V battery is usually mounted internally underneath the fingerboard. It is mounted in a metal clip – you just need to pull the battery to remove it from the clip. It is s good idea to have some sticky tape over the battery and clip to reduce the chance of the battery coming out of the clip by itself. The battery is connected to the controls by way of a set of connectors and a lead.
There is a battery life indicator (red) light on the controls which lights continuously when the battery is low and needs changing.
