CHEKING OF THE ROM VERSION While pressing the DOWN and MANUAL switches, turn on the POWER switch. The model name AG.S is displayed for about 2 seconds. As the version number *.** (each * representing a number) appears after that, check it. Then the mode will return to the normal mode.

ERROR MESSAGES

If an error occurs during operation, one of the following error message numbers will appear in the display. Stop operation of the AG-Stomp and follow one of the solutions described below.
E1: MIDI Receive Buffer Full
CAUSE: Too much MIDI data is being received and the buffer is full SOLUTION: Try reducing the amount of data being sent, or break the data into smaller blocks.

E2: Communication Error.

CAUSE: An abnormality is detected during MIDI communications. SOLUTION: Check all connections, etc. and try again.
E3: Bulk Receive Check Sum Error.
CAUSE: The check sum does not match the received MIDI bulk dump data. SOLUTION: Check all connections and transmitted data, and try again.
E4: Bulk Receive Data Abnormality.
CAUSE: An abnormality is detected while receiving the bulk dump. SOLUTION: Check all connections and transmitted data, and try again.

MARK OAKLEY:

JEWELS ACOUSTIC ACE
AS JEWELS NEW GUITARIST AND MUSIC DIRECTOR, Mark Oakley faces many sail-or-fail situations, like todays live appearance on the Rosie ODonnell Show. But he says he seldom gets uptight: Im never nervous, even in a situation like playing on Jay Leno, where if you screw up, youre screwed. Its just pure excitement. Part of Oakleys confidence stems from his years with two famed Nashville ensembles: the Sams Place house band and the Prime Time Country band groups that have backed such artists as Glen Campbell, Wynonna, Faith Hill, Dolly Parton, Amy Grant, Billy Ray Cyrus, Delbert McClinton, and Michael McDonald. Those bands would play behind a different artist every night, recalls Mark. We would have to learn a new set of songs for every show. Yet Mark says he relishes the opportunity to focus on a single group, as he previously did while serving as SHeDAISYs bandleader. I suppose its more challenging to play with a house band, but its often not quite as much fun as being part of a regular group, where you get a chance to get into the comfort zone with the material. Plus, everyone in Jewels band is an amazing musician, and theyre all fun to be around. In fact, Oakley insists, fun to be around is practically a job requirement for session and touring musicians. If people dont want to be around you, youre not going to get called no matter how good you are. You find if you work with the top session guys in Nashville that in addition to being amazing players, theyre always great guys. Another thing that makes the Jewel gig fun is the fact that the singer doesnt insist that the musicians reproduce every song exactly as it appears on disc. Ive been with artists who freak out if you dont play everything exactly like the record, says Mark, while others, like Jewel, want you to be creative. She lets the musicians be themselves, which is a lot more fun than replicating everything every night like a robot. I think thats better for the audience, too. If every arrangement is exactly like the record, they could have just stayed home. Im not talking about completely changing everythingobviously, there are signature parts that people want to hear. Im referring to subtle things that keep the music from sounding stale. Oakley estimates that he plays acoustic for 60% of Jewels current show. When he does, he straps on a Yamaha CPX15N. I have two of
them, and theyre both amazing, he says. Ive noticed that a lot of guitars that sound good plugged in arent so great when you track them acoustically in the studio and vice-versa, but these guitars are great both ways. Their sound is big, warm, and woody, which I vastly prefer to the overly bright and cutting sound you get from a lot of acoustic-electrics. Remember, its always easy to brighten up your tone with EQ, but you cant fake bigness and warmth if its not in the guitar. Live, Oakley runs the guitars through a Yamaha AG Stomp acoustic guitar pre-amp. The CPX has both a piezo pickup and an internal

microphone, which you can blend. But when I plug into the AG Stomp I use mainly the piezo, because its such a great-sounding combination. I usually use one of two AG Stomp programs. For strumming, I have a setting that is fairly compressed and has very little reverb. But its good to have a little more volume for fingerpicking because you dont want to have to play too hard, so I have a separate setting with a boost and less compression. Either way I keep the EQ pretty flat, because the guitar just doesnt need it. Oakley has one crucial piece of advice for young players who hope to someday be where he is: Get out and play in front of people as soon as you get a little playing under your hands. Almost every successful musician I know was playing in a high school band and whatnot. Dont sit in a room practicing scales for the first six years of your musical life.
