I agree. If you're just learning, effects will mask your mistakes and distract you from actually progressing. Cheapo basic amps (can usually be rented for $15-20/month or bought for under $100) or acoustic.

:edit: its the same concept as learning to autocross on R tires. You wont notice your mistakes, and you wont learn to correct them. Learn on basic stuff, when you've mastered that, and your skill warrants it, upgrade.
