Critic Reviews

Peavey 6505 Piranha review | MusicRadar

musicradar.com

Despite its small size, the Peavey 6505 Piranha packs a punch with impressive gain and tone, making it a solid choice for metal enthusiasts. The inclusion of an effects loop adds versatility, and the amp can handle small gigs with ease. However, its high hiss level might deter some home or recording users, and it comes at a higher price compared to the Orange Micro Dark. For those seeking clean tones, this isn't the ideal choice. Overall, the Piranha delivers signature 6505 metal tones, whether using humbuckers or single coils.
