DIRECT INPUT 
When using the MP-1 direct into a P A or recordingconsole and using distorted tones it may 
be necessary to use an outboard EQ to "emulate" the tone of a guitar speaker cabinet The 
following curve may help. 
+4dB@ 160Hz.,  -2dB@250Hz.,  -2dB@ 1kHz., 
+2dB@ 1.6kHz.,  -4db@2.5kHz.,  +4dB@4kHz., 
-8dB@6.3kHz. 
If your EQ has less bands concentrate on the following, in order of importance: roll off past 
4kHz., notch at 2.5kHz., and boost at 1.6kHz. A three band parametric in conjunction with 
most mixing board EQ's will get the basic curve. 
BACKUP/DOCUMENT 
Once you've put all that work into programming your MP-1, backup your memory with 
System Exclusive Bulk Dump. If you can't get access to a disk drive put pen to paper and 
document your work (an once of prevention is worth a pound of cure!)
