## Questions & Answers

**Q: Will this work for a vox vt30 valvetronix?**
A: It's the standard preamp tube used in just about every tube guitar amp.  it's also the same as an ECC83...  look up the tube currently in your amp, and google for cross reference tubes for other "models" that will work...  generally speaking, any of 12AX7, 12AT7, and 12AY7 will work in place of each other...  they will also work in place of an ECC83...  hope this helps...

**Q: Will this work for audible illusion modulus 2 pre amp**
A: No. You need the 6DJ8/6922 tubes for this amp.

**Q: Does this vacumm tube work with the presonus preamps?**
A: Yes, if your preamp requires a 12AX7 preamp tube then this will work well.

**Q: I have a crate gt80 non dsp amp. will this work in it?**
A: It looks like your amp takes one 12AX7 and two 12AU7's. This Electro-harmonix 12AX7 will work and you can find the 12AU7 on our page.
