I am new to this forum and I just signed up to see if anyone has had the problem with their Ibanez SR505 bass that I am currently having. My problem is regarding the preamp built into my Ibanez SR505that I purchased new in December 2006. My Ibanez SR505 has given me no trouble since purchasing in six years ago until two weeks ago when I started getting what I called a "volume spike." I use this bass to play in the church band where I attend church regularly. I have all of my EQ controls preset on the guitar the way I like them and the only knob that I ever have to touch at all is the volume control knob to adjust volume up or down for different songs. Two weeks ago my volume issues started occurring after 30 to 40 minutes of playing the bass in during the song service. The first time it happened I took the bass home and removed the back cover off where the EQ controls and wiring are and I blew that area out with compressed air hoping that it was just a dust problem. I had replaced the 9 volt battery around January 1st of this year but I took the battery out and tested it and it registered a full charge. I took the bass back to church this past Sunday and the same thing occurred another volume spike within 30 to 40 minutes of playing time. To correct this I reach down quickly and adjust the volume but it happened again within five minutes and I had to adjust the volume a second time. After the initial song service I always turn the power to my amplifier off and return to my seat in the congregation but I leave my guitar cable plugged into the bass. When I return to play my bass near the end of my church service, I turn my amplifier back on and the last two weeks I have heard a pop through the speakers of my amplifier and I never experience that in the last six years of playing this bass. I live in the Knoxville, TN metro area and I brought the bass home again. I contacted Ibanez support by email explaining my problem with the popping noise and the volume spikeing issues. Ibanez support replied by email saying that it sounds like the volume spikeing issue and the popping could be the preamp on the bass and that I would have to have it replaced. They gave me the part number (3EQ1CMK1) and a price of $208.00 for it which I could order from Ibanez online with a credit card. That part number includes the preamp and all 5 pots for the bass but I will still have a installation fee for who ever installs the preamp into the bass. The price for the preamp alone (and not including installation) is around a third of what I paid for the bass with a hard case $669.94. I do like this bass a lot for gospel music but I am a little upset about how much this is going to cost me to get it repaired. I don't know if I should have the guitar repaired or just trade it in on another bass that doesn't have the active EQ built in along with the 9 volt battery. I have contacted several music stores in the Knoxville metro area since this past monday and no one seems to work on Ibanez basses here with the exception of the local Guitar Center store. I told the guitar tech my problem over the phone and he said that it sounds like a problem with the preamp also. I asked the guitar tech if Guitar Center could order the preamp cheaper than $208.00. He connected me with another department and they took the part number from me and my phone number to call me back but I have not heard back from them yet. Is there anyone else in this forum that has experienced this particular problem with an Ibanez SR505 bass before? I do like this bass a lot but I don't want to put more money into it than it is worth to repair it. If anyone knows of anyone that works on Ibanez basses in the Knoxville, TN area other than Guitar Center please send me contact information. Also any other suggestions or comments would be welcomed.
