Minimum wattage to play with some buddies

[Azari]

No less than 1400 watts

IME, it really all depends on how loud your drummer plays, or if your guitar player is one of those “ I have to turn my amp up to 11 to get my tone, man! “ types.
I’ve hade 100 watt amps work just fine with some bands and others that a 300 watt amp wasn’t enough for basement rehearsals. The latter type meant wearing earplugs and lots of watts.

Good luck.

Exactly. The typical semi pro rig in the UK when I started playing was a 50W amp and a piss poor 1x15. It worked because it had to, there wasn't a choice. If you're playing with sensible people then even 20W and a 1x10 could be adequate. With my acoustic band I've even used a 1W amp and a 1x10. So there isn't really a minimum wattage. Lots of us play out with kit that the TB consensus would consider quite inadequate.

My main piece of advice is that this isn't a marriage. You can buy and sell amps as often as you like (some folks here have trouble selling) . As you don't yet have any strong views on what you need I would talk to your mates about what they think you'll need, and hopefully informed by that see what's on the local second hand market from a recognised brand. 50W or more, 2x10, 1x15 or more will probably do. If it's a recognised brand (eg Fender Rumble), you'll probably be able to sell fairly readily for much the price you paid if it doesn't suit. At this stage avoid the obscure and beginners practice amps, and don't go trying to second guess what you'll need in 6 months, 3 years, whatever.
