LM386 chips

[East Texas]

Hi everyone, first post here. I have been building pedals off and on for about 15 years, mostly on perf board or hand etched pcbs. I just completed my first pedalpcb circuit - a Paradise Overdrive. I love the sound of it, but the build doc recommends the LM386-3 and all I have been able to locate is the LM386-1 chip, which has about half the output (325 mWatts versus 700 mWatts.) So I was wondering if anyone has compared the sound of these 2 chips in this type of circuit? The chip I used has plenty of output and sounds glorious, but I just wondered if there is an audible difference in the two?

This is not my area of expertise, but I would think that you'd only get an audible difference under a heavy, heavy load. Remember that these chips are designed to drive 8 / 16 / 32 ohm speakers, not 100k volume pots.

A comparison would be worrying about driving a Ford F150 instead of an F250, when all you're hauling is your kids tricycle.
