Guitar Amp Cost: Practice, Gigging and Tube Amps (2026)

An electric guitar is the only common instrument that arrives incomplete. It makes a thin, private sound unplugged, and everything the player imagined when they bought it lives on the other side of an amplifier. That makes the amp a hidden second purchase, and it is the one beginners most often under-budget.

The good news is that the useful answer is cheap. A first amp should cost around $100, and spending $600 on one before you know what music you want to make is a worse mistake than spending $60.

What actually drives an amp’s price

Watts, but not the way people think. Volume does not scale with wattage in a straight line: a 100-watt amp is not five times as loud as a 20-watt one, it is roughly twice as loud. Watts buy headroom, which is how much clean volume you get before the amp starts to distort. A bedroom player needs almost none of it.

The circuit type. Solid-state amps use transistors and are cheap, light, reliable and consistent. Tube amps use valves, cost more, weigh more, and compress and break up in a way many players prefer and can hear. Modelling amps use software to imitate other amps, and the good ones now do that convincingly for a fraction of the price of the things they are imitating.

The speaker and the cabinet. The most-overlooked line in the price. The same circuit through a better speaker in a well-braced cabinet sounds substantially different, which is why speaker swaps are a common upgrade on otherwise cheap amps.

Practice amps: $60 to $200

Ten to twenty watts, one small speaker, a headphone output, and usually a basic overdrive channel. This is the correct first amp for essentially every beginner, and it stays useful forever afterwards as the thing you keep in another room.

The headphone jack is the feature that matters most and gets discussed least. It converts an instrument that annoys a household into one that can be played at eleven at night, and that single fact does more for a beginner’s practice hours than any tonal upgrade.

Modelling has moved down into this tier hard. A modern $150 modelling practice amp offers a dozen amp voices and built-in effects, which for a player still deciding whether they are a blues player or a metal player is worth more than one very good clean channel.

Gigging amps: $300 to $800

The jump to this tier is about being heard next to a drummer, which is a higher bar than most people expect. A 20-watt practice amp disappears entirely under an acoustic drum kit. Thirty to fifty watts of solid-state, or a good modelling combo, handles rehearsal rooms and small venues.

This is also the tier where a single purchase can cover everything. Modern modelling combos in the $400 to $700 band include amp models, effects, and a direct output for recording, which replaces an amp, a pedalboard and an audio interface for a player whose ambitions are mostly at home.

Tube amps: $800 to $1,500, and what the money buys

For a tube amp that is genuinely good rather than merely valve-equipped, the realistic budget is roughly $800 to $1,500. Above about $2,000 you are into high-end production and boutique builds, bought for a particular voice.

Tubes are not simply better. They are heavier, they run hot, they are more fragile in transit, and the valves are consumables that need replacing every few years at $50 to $200 a set depending on the amp. What they give in return is a response to playing dynamics, where hitting the strings harder changes the character of the sound and not just its volume, and a distortion character that decades of records have trained everyone to recognise.

The honest test: if you cannot yet describe what you dislike about the sound of a good modelling amp, a tube amp will not fix it.

New versus used

Amps are the best used buy in guitar gear, better than the guitars themselves. They have few moving parts, cosmetic damage is common and irrelevant, and a solid-state amp that works today will work in ten years. A $600 combo bought used at $350 is the same amp with scuffs.

Two things to check on a used tube amp specifically: ask when it was last re-tubed, and listen for crackle or hum at idle. Both are fixable, both are bargaining points, and neither should be a surprise after you have paid.

The costs that come after the amp

The cable is the one people forget, and the free one bundled with a starter pack is usually the first thing to fail. Headphones matter more than any tonal upgrade for a bedroom player. On a tube amp, add a re-tubing budget every few years. And if the amp ever leaves the house, it needs either a cover or the acceptance that it will collect dents, which affects resale far less than people fear.
