For those guitar players out there who use the Line 6 Vetta II amp (either combo or head version) there is a free upgrade available through Line 6. Firmware v2.5 offers, among other things, the following new goodies: Six (6) new amp models, including Orange and Dumble Seven (7) wah models in addition to one that you can customize (heel, toe, Q) A whammy effect called the Bender Solo boost function A ducking delay based on the t.c. electronic 2290 Fletcher-Munsen loudness curve More details plus installation instructions can be found at Vettaville. Make sure you download the latest versions of Line6 Edit (v3) and Monkey (v1.12) from Line 6 first. You'll need Edit to backup your patches (earlier versions will work but you'll need v3 to drop them back into v2.5 on the Vetta), and Monkey will manage the firmware installation process. Here is the Line 6 software page (just indicate Vetta combo or head in the pulldown). You can download the addendum to the Vetta manual here. If you don't already have a MIDI interface for connecting your Vetta to your computer the M-Audio USB Uno is very popular among Vetta users and works perfectly. Just be sure to connect it directly to your computer without a USB hub (something about the Line 6 software doesn't like them). I've only started playing around with the new features but the wahs alone are worth your time. Even if you don't like the new models at least you get to customize your own, unlike the original (which is still there by the way). That Line 6 listened to the feedback on the internet and actually implemented these changes - free of charge mind you - speaks very highly of the company in terms of their regard for the customer. Well done, Line 6.
