50w lower or higher small guitar amp for church

[electronoobz]

is 50W 1x2 amp loud enough for church? let's say 150 seats or more...

can you give me an easy but has a nice tube amp schematic?? well if tube is hard and expensive.. just give me a solid regular amp..

i always play every sunday.. so any help?? i will appreciate it so much..


i need an amp with treble/bass (or the high mid low) knob and the most important volume knob...

i mean 1x12 speaker.. not 1x2 sorry.. 15W would be fine for me
